One of my grans had the whole dementia thing too, I definitely sympathise with anyone going through that.

I have to say there were some funny moments in there, when she was busy chatting to imaginary dogs and telling us about how her and a friend bust out of the care home together to go to town (she couldn't go more than a step unassisted, her friend was wheelchair-bound and had had a stroke, there wasn't much happening there either). But generally, just absolutely horrible in all ways for all concerned. Sympathies to all of you!

Terrible disease, that.

Invite her over for your comfort, I think.
  Mayhaps.
